how do you attach a picture from computer to signature?

Oh my God, I've just been going through this. Done it before but I couldn't seem to manage it this time.

Easiest way seems to be to use pics from the rides section, so get some uploaded into the rides then when you clic them on you will be able to see the link.

Then get into user cp & put it in like this

 

Hang on a minute, I wrote the link & it put the pic up, here's an imaginary link.

Write it exactly like this except for your own link

 

It's done it again, I give up.

You'll have to ask someone else, I've had too much to drink.
